This study reported the impact of a locally isolated bacterium, Bacillus sp. strain SKC on the parameters affecting the properties of mortar. The abiotic control and bacteria-modified mortars were investigated to determine the differences in their properties. The compressive strength of the bacteria-modified mortar was successfully enhanced which was twofold higher than that of the abiotic control mortar, thus increasing the density. Calcium carbonate crystal deposition on bacteria-modified mortar reduced the porosity and permeability. The bacterial deposition of calcium carbonate was confirmed by SEM images and XRD analysis.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Abiotic controls,Adverse side effects,Aesthetic value,Bacillus sp,Bacterial deposition,Bacterial strains,Calcium carbonate crystals,XRD analysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Bacillus sp,Biocementation,Bioconcrete,Calcium carbonate,Compressive strength,Permeability,Porosity[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors acknowledge the members of the Geomicrobiology, Biomining & Biocorrosion Laboratory and Microbial Culture Collection Laboratory, Biosciences and Biotechnology Research Center (BBRC), Institut Teknologi Bandung for their cooperation and assistance.
